SPEGIFICATIONforming part of Letters Patent No. 703,510, dated July 1,1902.

Application filed December 19, 1901. Serial No. 86,526. (No model.)

To all whom it may concern.-

Beit known that I, WILLIAM N. WILLIAMS, a citizen of the United States,residing at WVelcome, in thecounty of Martin and State of Minnesota,haveinvented certain new and useful Improvements in Sleigh-Runners; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilledin the art to whichitappertains to make and use the same.

The invention relates to sleigh-runners.

The object of the invention is to provide a runner with an attachmentwhich shall be simple in construction, durable in use, comparativelyinexpensive of production, and easy of application, whereby side orlateral shifting of the runner will be prevented in traveling over hillsor inclines or making sharp turns at a great speed. With these and otherobjects in view the invention consists of certain novel features ofconstruction, combination, and arrangement of parts, which will behereinafter more fully described, and particularly pointed out in theappended claim.

'In the accompanying drawings, Figure l is a side elevation of thesleigh-runner embodying my invention. Fig. 2 is a top plan view, andFig. 3 is a vertical sectional view showing the position of thespring-bow when the runner is making a turn or rounding a curve andillustrating the dragging action of the bow.

Referring to the drawings, 1 denotes the runner of a sleigh or othervehicle or conveyance, which may be of any well-known or approvedconstruction and which may be equipped with shoes in the usual way.

2 denotes the attachment, which consists of a spring-bow, which, asshown in Fig. 2, is curved outwardly and projects downwardly for oneportion of its length, as shown in Fig. 1, so as to be below the lowerface or shoe of the runner and has its ends secured by bolts 3 to theinner side of the runner.

The weight of the load when the sleigh is drawn in a semicircular pathis thrown to the outside, and by attaching the bows to the inner sidesof the runners the bow of the outer runner is caused to spring inwardlyfrom the inner face of the runner, and in doing this exerts a varyingdrag upon the snow or ice, according to the surface overwhich the runneris traveling and the speed with which the turn is made. If the spring-bow were secured to the outside of the runner, in turning curves itwould be forced against the runner, thus creating a friction against therunner and causing it to stop in its sidewise movement too suddenly,which has been demonstrated in practice to result in the overturning ofthe load. It will thus be seen that a desirable advantage is gained bysecuring the spring-bow to the inner side of the runner.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of the invention will be readily un derstood withoutrequiring a more extended explanation.

Various changes in the form, proportion, and details of construction maybe made within the scope of the invention without do parting from thespirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The combination with a sled-runner, of a bow-spring having its oppositeends secured to the'innersurface of the runner and having its bodyportion curved outwardly with one portion thereof projecting downwardlybelow the lower surface of the runner, whereby saiddownwardly-projecting portion is capable of being sprung inwardly towardthe said runner when the sled to which it is attached is in the act ofturning a curve, substantially as specified.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
